I don't write that many negative reviews but when I really HATE a product I feel compelled to warn others. I really don't understand how my experience with this product is so different from others who seem to like it. According to the product description "it holds 40 tools" but I only have about 20-25 items in it, none of them are too heavy and the bottom of the shelf hangs so low in the middle that it won't even roll on the floor anymore . The vertical risers also flexed. I look like I'm putting on an entire Olympic set of free weights which I EXPECT to distort his form so much. But like the product photos, I only put light poles, poles and tools in the rack. See attached photo. It looks cramped, but most of the "tools" are made of plastic, wood, or aluminum (so lightweight). Pay attention to the sagging of the base and the curvature of the vertical risers. I hope this review helps at least one person avoid the disappointment I experienced with this 1 star product.
